Bravo said that he was attacked when trying to protect a woman with a child who allegedly prevented from passing by migrants. The vendors said that the fight was started by two drunken tourists who attacked the merchant, hit him with a bottle, and only then the US citizen and "another person with whom he was" got involved in the conflict.
